JAMES MARJERISON, OF LA\VRENOE, MASSACHUSETTS;

SPINNING- MACHINE.

SPECIFICATION forming part of Letters Patent No. 618,229, dated January 24, 1899.

Application filed February 21,1898. Serial No. 670,997. (No model.)

To all whom it may concern:

Be it known that 1, JAMES MARJERIsoN, of Lawrence, county of Essex, State of Massachusetts, have invented an Improvement in Spinningdllachines, of which the following description, in connection with the accompanying drawings, is a specificaiiomlike letters and figures on the drawings representing like parts.

The invention to be herein described is intended as an improvement on the class of machines shown in United States Patent No. 381,567, dated April 24, 1888. The patent referred to shows and describes a spinningframe employing caps which are set on deadspindles; and the invention therein contained com prehends means for simultaneously removing the caps and the wound bobbins in order that the latter may be doffed, and thereafter the tubes on said spindles have applied to them empty bobbins, and then the caps are returned upon the tops of the spindles. In this present invention I have devised novel clamps or devices to handle the caps and also the full or wound bobbins and the empty bobbins. The clamps shown in said patent consisted of levers connected between their ends by a pivot, so that each carried apair of pliers; but in practice it was found that such clamps made as levers of the first order could not be opened suiiiciently wide to adapt the clamps to all diameters of caps and of wound bobbins, and consequently said clamps have been improved.

My improved clamps present longer grasping portions, and said grasping portions are carried at the ends of two levers mounted at their opposite ends on a stud located at a considerable distance from the line of the spindies, and said levers Work in a guide which controls and steadies them .in their movement, said guide cooperating with said levers near their grasping portions, a spiral spring connected at its opposite ends with both of said levers normally acting to keep the grasp-' ing portions pressed one toward the other, but in a yielding manner, so that each concaved grasping portion may move independently of the other as it meets a cap, bobbin, or whatever is to be clamped.

The patent referred to was without means for holding the yarn between a full bobbin and the usual front rolls when the said bobbins were to be doffed and empty bobbins were to be applied to the spindles, so that a second set of bobbins could be quickly started. Herein, however, I have provided for the first time, as I believe, automatic means whereby when the clamps have grasped a wound bobbin and removed it from its tube on the spindle the yarn will be caught between the front rolls and the wound bobbins and will be put in such position that it may be clamped and held by the empty bobbins as they are put upon the tubes and'spindles, said clamped yarn being readily wound on the bobbins just applied to the tubes and spindles when the machine is again started, the tubes being rotated on the spindles by usual banding, common to said patent.

The means provided for catching the yarn and putting it in position to be clamped will be hereinafter more fully described.

In the patent referred to the clamps for engaging the caps to remove them from the spindles were carried by arms pivotally mounted on the ends of clamp-actuating levers, said arms normally occupying a position turned back, down, and away from the spindles, and they had to be turned up into operative position to enable the clamps to engage the caps and remove them from the spindles preparatory to other clamps engaging the wound bobbins and removing them from the tubes and spindles. These cap-holding clamps having engaged the caps and having lifted them from the spindles were again turned back, down, and away from the tubes and spindles, they continuing to hold the caps while the wound bobbins were removed by other clamps and empty bobbins were put back upon the tubes and spindles by yet other clamps, after which the arms having the clamps engaging the caps were again put back into elevated position, as described, to enable the clamps holding the caps to apply them to the tubes and spindles preparatory to spinning and winding the yarn on the bobbins just applied, and thereafter the levers carrying said clamps were IOO alley-way between the frames seriously obstructed the alley-way, which was very obj ectionable, because the alley-way space in all mills is limited and should be always kept open and clear. To obviate this trouble, I mounted the capclamps on bars carried at the upper ends of segmental toothed racks, said racks being fitted in guideways on levers to be described, and to put said bar carrying said clamps, it normally occupying its inoperative position, into its operative position I provide a shaft having gears to engage the teeth of said toothed racks, said shaft having attached to it at one end of the frame a hand-wheel, by which it may be operated. By this plan the alley-way is not at all obstructed. I have also provided novel means for supporting the clamps holding the empty bobbins. The clamps which hold the empty bobbins to put them onto the usual tubes carried by the spindles are peculiarly constructed. 2'. 6., they have each a projection or finger which as the clamps are being turned ofi laterally from the bobbins just put upon the tubes acts to partially rotate each bobbin, the extent of each rotation being just enough to enable the usual slots at the lower ends of the bobbins to engage and slip down on the usual bobbin-driving studs or lugs carried by the tubes, so that said bobbins are always properly seated on their driving-tubes, and in coming to their seats the heads of the bobbins clamp the threads then placed in position for said purpose by means of a thread-catcher and hold the yarn firmly with relation to said tubes as the latter are started to wind the yarn on a new set of bobbins. The yarn on the new bobbins is broken off automatically after a few turns of the bobbin and tubes, and thereafter the full bobbins are by hand taken out of the clamps holding them.

The thread-catcher is herein shown as composed of a rocking and sliding shaft having a series of hooked arms which are adapted to engage the yarns between the usual guideboard and the wound bobbins, and by a lateral movement of the thread-catcher they bear the yarns held by them laterally against the tubes, so that when the empty bobbins come into position on the tubes the said yarns are each clamped by the bobbin. Herein I employ for moving the various clamps camplates and levers which differ but slightly from the cams and levers employed in the patent referred to, the cams herein shown having longer slots and slightly difierently shaped chiefly to provide for longer bobbins.

Figure 1 is a partial front elevation of one end of a spinning-frame, showing some of my present improvements. Fig. 2 is an elevation looking at the machine shown in Fig. 1 from the right. Fig. 3 is a detail in front elevation showing part of a spindle, a cap, a bobbin, part of the bobbin-rail, and part of the thread-catcher in position. Fig. 3 is a section of the sleeve removed from the deadspindle. Fig. 4 is a detail showing the empty bobbin-clamp as having put a bobbin onto 4 that the empty bobbin may clamp the yarn I preparatory to spinning a new set. Fig. 5 is a detail in plan View of the cap-clamp. Fig. 6 is a detail in plan view of the clamp for engaging and removing the full bobbins. Fig. 7 is a detail looking at Fig. 1 from the right of the line to. Fig. 8 is a detail looking at said figure from the right of the dotted line cc, and Fig. 9 is a detail looking at Fig. 1 from the right of the dotted line 216 Figs. 10 and 11,a perspective view and section of the clamp holding the dead-spindle to the builder-rail.

The frame A, the bottom rail A, extended from one to the other end of the frame, the spindle-rail A carrying the dead-spindles B the builder-rail d supporting the bandreceiving portions of the tube 24, having suitable lugs 26 to enter the usual grooves in the lower ends of the bobbins (1 the cam-plate f for actuating the clamps for carrying the empty bobbins, the lever f, having a pin f, entering the slot of said cam-plate and fixed to the rock-shaft e, the cam-plate h, having cam-grooves and receiving the pin 15 of a lever h, loose on said rockshaft c", said lever and cam being employed to actuate the clamps for taking off the full bobbins, are and may be all substantially as shown in said Patent No. 381,567, with the exception that the grooves in the cam-plates referred to are somewhat differently shaped and made somewhat longer to thereby adapt the machine to longer bobbins. These cam-plates and other cam plates to be described are suitably erected on the bottom rail. The builder or copping rail (Z will in practice be raised and lowered to suitably wind the yarn in bobbin form by mechanism substantially such as shown in said patent, or it maybe by any usual builder mechanism commonly employed in spinning-frames. The bottom roll A and the leather-covered top roll A between which the yarn passes on its way toward and through the usual eye in the guide-board A to the bobbin to be wound thereon, are and may be all as common in spinning machines. In Figs. 2, 7, 8, and 9 this guide-board is shown as turned up in its inoperative position; but it is shown by dotted and full lines in Figs. 2 and 3 as turned down into its operative position.

Referring now to the devices for handling the empty bobbins, the rock-shaft c has fast on it a hub having a projecting arm 71 which receives a pivot h, on which is mounted a lever 71 having at its lower end an elongated slot which receives a bolt h so that by loosening said bolt and turning said lever Won said pivot it its upper end will be placed near to or farther from the spindle, as may be desired. The lever it has a stud it, upon which is mounted the lower end of an arm 72, slotted as at it said slot being entered by a guiding- IIO stud 71, so that said arm can turn on said pivot and move longitudinally or in the direction of the length of the spinning-frame. A bar h has attached to it a series of emptybobbin clamps composed of two membersv h and 72, the member 71 being pivoted to the member h at h Each of these members has a concaved portion to embrace properly the barrel of the empty bobbin (Z and the part 72, has a projecting lug or finger 71 (see Fig. 4,) and the free end of said part h is kept pressed toward the bobbin grasped by it by a suitable spring 7i.

The portion 7b of the empty-bobbin clamp has a horizontally-extended lug 72. against which the lower end or head of the bobbin d stands when the said bobbins are applied in said bobbin-clamp, said lug enabling the heads of all the bobbins to be placed at the same level and also prevent any liability of the bobbins from being dropped down out of the position in said clamps, so that they might strike the spindle when the arms and levers carrying said bobbin-clamps were being put into position to apply empty bobbins to the spindles.

The bar h has attached to its under side a slotted curved plate 77. said plate receiving a roller or other stud 76 suitably connected with a bar h ,carrying the full-bobbin clamps, to be described. The bar if has connected to its end a metallic yoke-shaped piece 72 (see Fig. 9,) said yoke having a rounded pin 71 which is embraced loosely by the slotted upper end of a lever 7L (see the right of Fig. 1,) mounted on a pivot h icarried bya bracket h carried by the rack D said lever being provided at its lower end with a slot in which is adjustably confined a roller or other stud W said stud being adapted to work in the irregular cam-groove 71 made in a cam-plate h said plate having suitable switches 7L and 7f to control the movement of said stud 71 and at the proper time to vibrate the lever 7L so that when the rock-shaft e rises, as provided for in said patent, the roller-stud will travel vertically in said slot, and when it descends it will strike the switch 7L30 and move into the inclined or irregular part 40 of said slot, passing finally into the part 41 of the slot, and thence under the switch 73 into the lower straight part of said slot. During thismovement of the lever 70 about its pivot 7B the said bar 70 is slid longitudinally, carrying with it,through the roller Withe bar 7: on which is mounted the empty-bobbin-carrying clamps. It will be noticed that the movement of this bar while the roller 7L2G is passing from the switch 71 beyond the switch. 7t is first to the right, viewing Fig. l, and then back to the left again.

Fig. 1 shows the stud 71. standing in the truly-vertical part of the slotin the cam-plate 71 the empty-bobbin clamps at such time standing with their bobbins at the left-hand side of the spindles B containing the full or wound bobbins. As the rock-shaft c rises,

however, taking with it the bar h carrying said clamps, to put the heads of the bobbins about the tops of the spindles, the roller 26 passes the switch h and as the shaft 6 starts to descend said roller meets said switch again and the bar h is turned, causing the connected bars 71 and h to be moved quickly to the right, thus putting the empty-bobbin clamps, with their empty bobbins, directly opposite the spindles containing the full bobbins, it being assumed, as will be described hereinafter, that the full-bobbin clamps engaged the full bobbins and removed them from the spindles while the stud 72, was rising in the vertical part of the slot, and while the em pty-bobbin clamps are opposite the spindle the lever f will be moved by the shape of the cam-slot in the cam-plate f and the clamps and bobbins will be carried toward the spindles, and said empty bobbins will be put over the tops of the spindle and onto the tubes carried thereby by the descent of the rock-shaft a, the roller h then traveling in the part of the cam-plate 71 and during such movement the rock-shaft e is also turned by the cam-plate f in a direction to move the said empty-bobbin clamps away from the spindles, the resulting two movements causing the finger h", connected with the portion h of the empty-bobbin clamp, to be drawn off from the empty bobbin in a diagonal path, so that the said finger h operates against the side of the empty bobbin and rotates it about the tube until the slotted lower end of the bobbin correctly engages the driving-lugs 26 of the band-receiving portion of the tube 24, so that said bobbin may be immediately thereafter taken up and rotated in unison with the said tube. At this point I will describe the manner of confining the yarn correctly with relation to the empty bobbin and tube, so that the yarn may be wound properly on the empty bobbin. To do this, I mount in the machine a rod (1, one end of which is exposed at one end of the machine, where it is provided with a suitable handwheel (not shown) by which to turn it. This rod has fixed on it in suitable manner a series of thread-catchers a. These threadcatchers normally occupy when the frame is running regularly the position shown by dotted lines in Fig. 2 and full lines in Fig. 3, a thread-catcher lying near one side of each of the separators a, as represented in the full-line position Fig. 3. V

lVhen the operator is ready to doff a lot of full bobbins, the frame then standing still, he will engage the rod or rock-shaft a and will move it toward the left-hand end of the machine from the position Fig. 3 into the position at the opposite side of the full bobbin, so that the little notch (L in the end of said thread-catcher will engage the thread between the usual thread-eyes of the guide-board A and the f ullywound bobbin and will carry it to the opposite side of the bobbin, and then the rock-shaft n will be turned to move the thread-catcher from its dotted-line position Fig. 2 into the dotted-1ine position Fig. 3, and the full bobbin is then taken hold of by the full-bobbin clamps, and the clamps are actuated to remove the bobbins from the spindles. WVhile the full bobbins are being taken off the spindles, or just after they are off, the operator pulls the rod again to the right, from the dotted-line position, Fig. 3, into the fullline position in Figs. 1, 2, and 4, thus leaving or putting said thread between the catcher and the full bobbin, against the tube above the lugs 26, and in this condition when the empty bobbin is put upon the tube 24 and is seated, as has been hereinbefore described, on the lugs, bya partial rotation of said bobbin on said tube the thread is clamped firmly between the lower end of the empty bobbins and the part of the tubes carrying the lugs, so that when the tubes are again started in rotation the yarn held as stated will travel with the tubes and will be applied to the bobbins, the first two or three rotations of the tubes breaking off the yarn between them and the full bobbins then held in the full-bobbin clamps, and thereafter the full bobbins may be removed by hand in any usual manner from the clamps holding them. After the tubes have been started in rotation to wind the yarn upon the empty bobbins just applied to them the operator, by hand, turns the rod (L20 to again put the thread-catchers in their inoperative position, as represented by dotted lines in Fig. 2 and full lines in Fig. 3. The caps 33, substantially like those represented in said Patent No. 381,567, are adapted to be engaged by the cap-holding clamps Z7 composed of two like jaws at the ends of levers D pivoted at theirouter ends each on a stud b each of said jaws presenting (see Fig. 5) a concaved portion with an outflaring lip Z2 The studs Z2 rise from arms Z7 secured to a bar or rail 20", each of said arms presenting at its inner end a rigid guiding-loop Z1 in which the levers Z2 are freely movable, said loops guiding and supporting said levers between the studs and their concaved acting portions or ends. Each of these levers'b has a suitable stud over which is caught the opposite end of a spring Z2 said spring controlling both parts of said clamp and enabling either lever to move, if required, in excess of the other lever, to thereby enable the jaws to properly adapt themselves to the cap.

The bar w has attached to it at suitable intervals segmental rack-bars I), which fit suitable guideways Z2 carried by the upper ends of levers U mounted to turn loosely on the rock-shaft 6, each of said levers having at its lower end, as herein shown, a projecting arm 12 having a slot in which is placed the roller or other stud 10 which enters and slides in a groove 12 in the cam-groove plate 10, said plate having a switch b ,controlled by a spring 12 The levers I) have suitable bearings to receive a shaft Z9 provided with pinions Z1 one for each segmental rack Z2 The shaft has mounted on it loosely the hub of an arm Z1 having a pin Z1 entering a hole in the part of the guide-plate 6 attached to theupper end of the lever 13 and said shaft, at the right-hand side of the hub of said arm, has fixed on it a collar 11 A spring b surrounding said shaft Z1 acts normally to draw the said shaft toward the left, viewing Fig. 1, keeping the pin 1) in the hole in the said guide. During the time that the spinning-frame is spinning yarn and winding the same the segmental bars b stand in their lowered positions, leaving the clamps 1) down in position nearly opposite the bobbins being wound, and when it is desired that the clamps shall engage and remove the caps 33, or it may be a fiyer, such as represented in my patent No. 381,566, then the operator engages a suitable hand-wheel on the shaft Z2 turns it, causing the gears b in engagement with the teeth of the rack-bars b to elevate the cap-clamps, and then the rook-shaft e is raised, whereupon the roller-stud 10 rises in the said slot and meets the switch Z9 which acts to quickly turn the clamps toward the caps, forcing the clamps onto and so as to embrace the caps firmly, said caps engaged by the said clamps being removed from the upper ends of the spindles as the rockshaft e continues its rising movement.

Fig. 8 shows the cap removed from the spindle and partially elevated; but the said cap will in practice be carried up above the rolls A or until the roller-stud 20 arrives in the upper end of the cam-slot Z1 The clamps 11 hold the caps 33 firmly, and when the rock-shaft e is again lowered at the proper time, the full bobbin in the meantime having been removed and an empty bobbin having been applied to the tubes on the spindles, the said caps are put upon the tops of the spindles, and after the rock-shaft c has arrived in its lowermost position and the levers Z1 have been moved to the left, viewing Fig. 8,to pull the clamps laterallyfrom the caps the operator engages the arm Z2 and moves it to the right, thus removing the pin 19 carried by said arm, from underneath the rackbar If", where it stood to hold up said rackbar during the operation of dofiing, the removal of said pin from underneath said rackbar permitting the rack-bar to descend again into its normal position. During the descent of this rack-bar its teeth remain in mesh with the teeth of the gear Z1 the teeth of said gear being long enough to remain in mesh with said rack-bar notwithstanding the 1011- gitudinal' movement of the gear with the shaft Z2 the spring 11 permitting this movement of the shaft 11 I will now describe the action of the clamps for engaging the full bobbin and removing the same from the tube on the spindle. These clamps I have lettered h One of them is shown in plan and detached in Fig. 6, and it 1s composed of two concaved jaws carried each by an arm mounted to turn on a studscrew 0 in the under side of an arm 0 attached by a suitable screw inserted in practice in the hole c in the arm 0 said screw entering a suitable hole in the bar W said arms having each a suitable stud or groove with which are connected the opposite ends of a spring 7t, said spring normally acting to keep said jaws closed, but permitting them to yield as the acting free ends of said jaws meet the surface of the wound bobbin as the said jaws are being moved toward the said bobbin to grasp it frictionally. The bar 71 carrying said clamps, is mounted on the upper end of a suitable arm 0 pivoted at c on a lever 0 pivoted at 0 on an arm of a hub 0 loose on the shaft 6 the lower end of said lever c havinga slot which is entered by a bolt 0 said bolt serving to secure said lever in any desired adjustable relation to the lever 71., mounted loosely on the rock-shaft e, and having the roller or other stud l5, entering the cam-slot in the cam-plate 7a The lever 0 is adjusted,when desired, to normally keep the front edges of the jaws or clamps substantially close to the surface of the wound mass of thread on the bobbins, so that when said clamps are moved to embrace and grasp the wound bobbins the extent of movement may be reduced to the minimum.

Assuming that the shaft e is in its lowest position and the stud 15 is in the bottom of the slot in the cam-plate h, then in this condition the clamp 71 will stand a little below the spindle-rail A and as the rock-shaft e is raised the pin 15 soon arrives opposite the little projection 0 and as said pin travels through the part of the slot marked 0 the clamps h will be moved from the position Fig. 7 to the right to engage the full bobbins, and as the rock-shaft e continues to rise the said pin will rise through the part c of said slot, the clamps at such time in engagement with the full bobbins acting to lift them vertically off from the tubes and spindles, .the caps having been previously removed, and, finally, when the full bobbins have been fully removed the pin 15 passes the free end of the switch 0 and immediately thereafter the weight of the full bobbins removed from the tubes and spindles is suflicient to cause the levers e and h to turn on the rock-shaft 6 until the pin 15 meets the straight side 0 of said cam-plate. Now it has been described that the empty-bobbin-carrying clamp moves to the right to bring its bobbins into position opposite the spindles from which the full b0b bins have just been taken, and during this movement the bar 7L carrying the full-bobbin clamps, they containing full bobbins, is also moved with it to the right, the jointing of the lever 0 to the lever c permitting-of this movement. The main shaft D is supported in suitable bearings D from the bottom rail A. This shaft may be driven by power in any usual manner to operate the machine so that it will rotate a certain number of times in one direction, and then it may be reversed to rotate a certain number of times in the opposite direction. This shaft has a pinion D and when said shaft is rotated to move the pinion in the direction of the arrow near it in Fig. 9 the rack D carrying the rock-shaft e, is raised in order that the difierent levers and devices carried by it maybe raised in the act of removing the caps and taking off the full bobbins, and when the I shaft is lowered the empty bobbins may be put on and thereafter the caps put in position on the tops of the spindles. To do this, the shaft D has substantially two rotations in one direction and then two rotations in the opposite direction. This shaft in practice is put under such control that it may be stopped at any position no matter what its direction of rotation.

The spindles B are confined to the builderrail in novel manner. Usually each spindle been been held in place by a set-screw inserted in the rail, its end acting against the spindle. Herein each spindle has its lowest end provided with a screw-thread 101, (shown in Fig. 8,) which is screwed into a threaded part of a split or clamping nut 102, provided with a clamping set-screw 103, which may be set up to hold the lower end of the spindle in ad justed position. The nut 102 has adj ustably attached to it by a set-screw 105 a lipped finger 104:. The spindle may have its foot set in the threaded hole 106, and the spindle may then be put up through the hole in the builder-rail until the nut meets the under side of the said rail, and the lipped finger will then be confined in position with its lip on the upper sideof the rail, and the spindle when adj usted to put its top at the proper level will be held firmly by turning in the set-screw 103.
